which with the other necessary adjuncts of themachine, makes acumbersome product,

difiicult to transport, and more difiicult, if

notimpossible to repair when fractured or broken. I v

In elimination of these disadvantages, the present invention consists oftwo side plates 1 and 2, having suitable flanges 3 and 4, on the bottom,provided with bolt holes 5 and 6, for fasteningthe same to a suitablesupporting structure. These plates are tied together at one end by ashaft 7, and rod 8, carrying a spacer tube or pipe 9, and at the otherend by a trunnion-10, the shaft 7, and trunnlon 10, serving additionalpurposes to appear hereinafter. Between and fulcrumed in said plates byfulcrum pin .or shaft 11, which also serves to tie said plates, is alever 12,,of cross-sectionally U-shaped structure at oneend, as'seen inFig. 3,embracing and connected by a pin 13, with a strut 14 to Iwhichreciprocatory motion "is imparted.

Generally the base in the ordinary class of through the medium ofaneccentric 15,

turned or fastened on, said shaft 7, which carries on the outside ofsaid plates, the

leys 17 and 18, respectively. The lever 12, as

seen in Fig. 3, has a double bearing on the strut, whereby the frictionis reduced to a minimum andthe wearing life increased, the

pin 13, serving principally to connect the lever with the-strut. On saidlever 12, is removably fastened a crushing shoe 19, by counter sunkheadbolts 19. The plane of said shoe is'ribbed orvcorrugated for a portionof its length, asat 20, and terminates in a curve 21, at a pointbelow'said ribs or corrugations. .T he aforenamed trunnion 10, forms apivotal support or bearing for a jaw 22, to which is arranged to beremovably attached by countersunkbolts 23, a die plate 23', having aplane, ribbed or corrugated,as

at 24, and terminating in a substantially compound or ,ogee curve 25,cooperating with said curve 21,. of said shoe 19, to levigate therockior ore. The disposition of said shoe 19, anddieplate 23, is insubstantially the form of a Y,.the crushingof the rock, fed from ahopper 26, immediately above said shoe and die plate, proceedingregularly and uniformly until thejpoint be.- tween the oppositelydisposed and interact; ing curves 21 and 25, is reached, where'the.final trituration takesp'lace, and the finished product discharged belowsaid shoeanddie the crushingand breaking of the rock occurs by areciprocatory motionof the lever, while the levigation-of the rockoccurs by a grinding motion of the curv'e'of the shoe against the curveofthe die plate, such motion being end ofthe curve .21, ofthe Shoe isvirtually concentric, or nearly so, with the are described by themovement of the lever around the fulcrum point, While the rest of thecurve is eccentric to such are.

Between the face of the lever 12, and the shoe 19, and also between theface of the jaw 22, and the die plate 28, is preferably interposed alead filling or sheet, for the purpose of forming a perfect seat'for theshoe and die plate, the rough and unplaned surfaces of which readilyembed'themselves into this plastic'layer.

The die plate 28, normally rests a.

is pivotally hung on the trunnion 10,

thus always ,connected in a pivotal manner portion of said jaw, at therear and at api proximately a point opposite the compound curve of thedie plate 28, is furnished with an integral abutment 28, which bearsagainst a thrust bar 29, transversely disposed elongated slots 80, andheld in position by cotter pins 81, or in any other suitable manl chine.

ner. Adjustment of the thrust bar 29, to regulate the degree offinenessof the pulverized product, is effected by adjusting screws 82, extendinglongitudinally of each plate and'locked in position of adjustment bylock nuts The said thrust bar '29, may be of cast ironor any othermaterial calculated to resist the 'strainincident upon the crushing ofrocks and ores of ordinary hardness, but incapable of withstanding anyexcessive pressure, such as wouldresult from the operation of the leveron metal substances or objects, as steel, iron, and the like, or in factany, not intended for treatmentby this mathe thrust bar will break, andpermit the jaw to swing on itstrunnion, thus insuring the otherivitalparts of the machine against breakage.
